Audio amplifier series

LPA4809

General Description
The LPA4809 is a dual audio power amplifier capable of delivering 140mW per channel of continuous average power into a 16Ω load with 0.1%(THD+N) from a 5V power  supply.  Boomer  audio  power  amplifier  was designed specifically to provide high quality output power with a minimal amount of external components. Since the LPA4809  does  not  require  bootstrap  capacitors  or snubber networks, it is optimally suited for low-power portable systems. The unity-gain stable LPA4809 can be configured  by  external  gain-setting  resistors.  The LPA4809 features an externally controlled, active-low, micro power consumption shutdown mode, as well as an internal thermal shutdown protection mechanism.
